What should you have?

Enter three things and see exactly what your household needs to get through 3 days, 1 week, 1 month or 90 days.

Nothing you enter leaves this browser except the ZIP, which we use only to look up today's hazards. We plan every person as an adult and every pet as a medium dog, so small pets and children come out a little over. That's the safe direction.

Your plan

Energy: cook, see and stay safe without the grid

⚠ Safety first

  • Never run a generator, grill, camp stove or charcoal indoors or in a garage, even with the door open. Keep generators far from windows and doors.
  • Put battery smoke and CO alarms on every level.
  • Store fuel only in approved cans, outside living space, within your local fire code limits (check with your county fire marshal). Date-label and rotate fuel.
  • Many cheap handheld radios (for example Baofeng) need an amateur radio license to transmit. FRS radios need no license; GMRS needs an FCC license with no exam.
